PENCIL-BOX.

SPECIFICATION forming' part of Letters Patent No. 589,762, dated September *7, 1897.

` Applgation filed Julie l5, Serial. N0. 595,582. (N model.)

To all whom] t incl/y concern:

Be it known that L ANDREW THOMPSON, a citizen ofthe United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvementsin Pencil-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in boxes and locking-covers therefor, the same being especially designed for use as a receptacle for holding pencils and the like, which is stron g and durable and will not become detached easily.

The invention consists of a box having a main cover `pivoted to the upper side thereof in an elongated slot adjacent to one end, an angularly-disposed strip on the upper side of said cover having recesses in the opposite edges thereof, supplemental covers pivoted to the outer ends of said box and mounted to rotate upon the upper surface of said main cover,'lockingstrips slidingly mounted in the adjacent ends of said supplemental covers, having tongues upon their under sides adapted to engage the recesses in the angularlyarranged strip on said main cover.

The invention also consists in other details of construction and combinations of parts,

which will be hereinafter more fully described and. claimed.

In the drawings forming part of this speciiication, Figure l represents a perspective View of my improved device, the parts being shown in their closed positions. Fig. 2 is a similar view with the parts shown in their open position, broken away at certain points. Fig. 3 is a bottom plan view of one of the supplemental covers. Fig. 4 is a vertical longitudinalsection through the device in its closed position. Fig. 5 is a cross-section through the same.

Like reference-num erals indicate like parts in the different views.

The box 1 is formed with a flat top and bottom, and has a main cover 2 mounted upon the upper side thereof, the same being secured iu place by a screw 3, passing through an elongated slot a at one end of said cover. The opposite end of said cover has a tooth or projection 7 thereon, which is adapted to fit Within a recess 6 in a ledge on one end of the box. On the upper side of the main cover 2 is securedan angularly-disposed strip 8, having notches or recesses 9 in its opposite edges and at opposite ends. Pivotally mounted upon the screw 10 at one end of the box 1 and upon the screw 3 at the opposite end thereof are two supplemental covers 11 11, having dovetailed recesses upon their adjacent ends, Within which fit dovetailed tongues 12 12 upon the under side of sliding lockingstrips 13 13. The said tongues 12 are adapted to engage when the parts are in their locked positions the recesses t) 9 in the strip S.

In closing my device the main cover 2 is turned upon its axis and afterward slid outwardly, so that the toot-h or projection '7 thereon nts within the recess 6 in the ledge 7. The supplemental covers 11 11 are then thrown around into the position in which they are shown in Fig. 1, and the sliding locking-strips 13 13 thrown outwardly, so that the tongues 12 thereon itwithin the recesses 9 in the strip 8. When in this position, the parts are securely held in place and cannot become detached accidentally. To open the box, a reverse operation to that just described should be performed.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination `with a box, of a main cover pivoted at one end to said box, a pair of supplemental covers pivoted to the ends of said box an d movable upon the upper surface of said main cover and means for locking said supplemental covers to said main cover, substantially as and for the purpose described.

2. The combination with a bos, of a main cover therefor pivoted in an elongated'siot to one end of said box and having a tooth or projection upon its opposite end which is 9 posite ends of said box and movable upon IOS) their pivotal points upon the top surface of speeiiezttion in the presence of two subscribsztid main cover and sliding looking-strips on ing Witnesses.

said supplemental covers havin" touffues T T f i i T upon their under surfaces which ae adated AB DRE FHGMPSOB 5 t0 t Within the recesses in said strip, sub- Vtnesses:

stantiztlly as :tud for the purpose described. M. N. HECKSCHER,

In testimony whereof I have signed this JACOB SCHNELLBACH.
